Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a guardrail cleaning device in which a brush device is mounted on a vehicle to clean guardrails on the left and right sides of the vehicle.

[Prior art and problems] Conventionally, a brush was loaded on the undercarriage and a device was used to clean the guardrail on the side of the vehicle while the vehicle was running.
There is No. 0418, but this device beam (it is designed to clean only the guardrail on the left side in the direction of travel of the image, and it is used when cleaning the guardrail on the right side of the road or the guardrail installed in the median strip) requires vehicles to drive in the opposite direction, which can obstruct traffic or cause accidents from oncoming vehicles.

Furthermore, the arrangement and functions of the slide base moving device on which the brush device is placed and the actuator that rotates the brush device are limited so that the brush device is stored on the left side of the chassis and protrudes to the rear left during work. Because of this configuration, it was not possible to move the brush device to the right side, and it was not possible to install the planar device on both sides because the operating device would be complicated and the vehicle would also be large.

[Means for Solving the Problems] The present invention moves a slide base that moves the chassis t laterally and a brush device provided on the chassis to symmetrical positions on both sides of the chassis, and rotates the brush device. By providing a turning device that changes the direction of the turning actuator so that the operating end of the turning actuator can be attached to either the left or right end of the slide base depending on the moving position of the brush device, the brush A common actuator can be used to operate the device when it is moved to a symmetrical position on the vehicle.

During cleaning work, the movable actuator 5 and the swing actuator 7 push the brush device 6 from the storage position shown by the dashed line in FIG. The moving actuator 5 is operated according to the distance between the vehicle and the guardrail, and the position of the slide base 4 is adjusted.

The slide base 4 can move the undercarriage in the left and right direction over almost the entire width along the rails 3 by means of rollers 41, and a support post 42 for the brush device 6 is provided in the center of the slide base 4. A moving actuator 5 and a turning actuator 7 are provided at each end.
Holes 43, 44 are provided for mounting (holes are not shown for the right end mounting).

The moving actuator 5 is supported on the rail 3, for example, with a bias towards the right side of the chassis, and is supported on the center side of the chassis.
The connecting plate 52 provided at the end of the operating rod 51 is attached to the right end of the slide base 4, which has been moved to the left side of the vehicle chassis 2, through a hole (not shown) with an attaching screw 53.

The brush device 6 includes a support tube 61 surrounding a support post 42 fixed on the slide base 4, a support arm 62, and an elevating actuator 64 for operating the brush 63 and the support arm 62. Water and detergent are fed by a compressor 11 through piping (not shown). Reference numerals 66 and 67 are connecting ears provided at the lower part of the support tube 6I, 68 is a connecting bin, and 69 is a hydraulic motor for rotating the brush.

The turning actuator 7 that rotates the brush device 6 has a slide piece 72 inserted through the operating rod 7■ connected to a connecting ear 66 at the bottom of the support If861 of the brush device with a connecting pin 68, and the slide piece 72 and the operating Rod flange 7
A spring 74 is inserted between the two. 75 is a stopper.

This swing actuator 7 is connected to the support bin 7 of the support frame 76.
The mounting plate 78 is supported by a mounting plate 78 through a mounting hole (not shown) provided at the right end of the slide base 4 with a mounting screw 79.

The swing device 8 includes a support base 81 fixed to the center of the vehicle chassis 2.
A support plate 83 is supported by a hinge bin 82 on this support base and can be raised and lowered in both the horizontal and vertical directions, a support shaft 84 is provided in the center of the support plate 83, and a rotation is rotatably attached to this support shaft. A moving plate 85 is provided, and a fixed fork 86 and a movable fork 87 are provided at both ends of the rotating plate 85, respectively, for holding the turning actuator 7 therebetween. 88 is a set screw.

(Operation) When not working, the brush 63 is connected to the lifting actuator 6 as shown by the dashed line in FIGS. 1 and 2.
4, and the support tube 61 is pulled up by the slide base 4.
At the same time, pull in the center of the support tube 6 to the point A position in FIG.
1 in the direction of the arrow in FIG. 3, and the brush 63 is stored in the empty space of the chassis 2.

When cleaning the left guardrail, as shown in FIGS. 2 and 3 at the work site, the moving actuator 5 pushes out the slide base 4 via the connecting plate 52, and the support tube 61 is moved to the left reference position iB. After adjusting the height of the brush position with the lifting actuator 64,
When operating the swing actuator 7, push out the lobe door I.
The slide piece 72 is pushed by the spring 74, rotates the support cylinder 61 in the direction opposite to the arrow in FIG. let In this state, the reference position of the surface slide base 4 is set so that the brush 63 protrudes to the left side of the vehicle 1 by, for example, about 75 cz.

The vehicle I is run so as to maintain an interval of 1 ftT, for example approximately 70 cz, which is slightly smaller than the protruding dimension of the brush from the guardrail. In this case, the distance sensor 9 attached to the vehicle body detects the distance from the guardrail G and displays it on the meter in the driver's cab, and the driver's cab only needs to drive while maintaining a predetermined distance from this meter. . The brush 63 is connected to the hydraulic motor 6 while supplying detergent and water as the vehicle travels.
Rotate at 9. Brush 63 contacts guardrail G
Then, the brush device 6 is pushed by the guardrail G and supported n.
61 as the center, the slide piece 72 is pushed back in the direction of the arrow in FIG. The brush device 6 swings to maintain brush contact even when the guardrail is uneven or when the vehicle and the guardrail slightly approach or separate.

The brush device has a constant angle of inclination with respect to the direction of travel, for example 6
The brush device is designed to maintain contact with the guardrail at an angle of about 0° to 45°, but if the vehicle approaches or moves away or the guardrail bends, the angle of inclination of the brush device becomes too small or too large beyond the above-mentioned certain value. Since the position of the slide piece 72 is largely biased through the connecting ear 66, a brush angle detection sensor (not shown) installed between the support tube and the slide base or between the slide piece and the stopper causes the spring 74 to be
It is detected that the adjustment range has been exceeded, and a signal is sent to the moving actuator 5 to move the entire slide base and correct the position.

When cleaning the right guardrail, tighten the set screw 088 of the 4'' turning device 8, sandwich the turning actuator 7 between the fixed fork 86 and the movable fork 87, pull out the connecting pin 68, and remove the slide piece 72 and the connecting ear. 66, and while holding the rotating actuator 7 with the fixed fork 86 and the movable fork 87, the support plate 83 is raised vertically about the hinge bin 82, and the support plate 77 is attached by removing it from the plate 78 and lifting the turning actuator 7 upward.

Next, the mounting screws 79 are removed and the mounting plate 78 is removed from the slide base 4. Further, the mounting screw 53 fixing the connecting plate 52 of the moving actuator 5 to the slide base 4 is removed and the operating rod 51 is rotated to bring the connecting plate 52 into an upright state. This operation creates a passage for the brush device between the rails 3 and 3, and with the lowering actuator 64 pulling the brush 63 northward from the turning device 8, move the brush device 6 along the rail 3 with the slide base 4. Push it to the right to move the center of the support tube 61 to point D, and turn the brush device 6 to make the brush 63 protrude to the right side of the chassis.

When the slide base 4 moves to the right side, the operating rod 51 of the moving actuator 5 is pulled in, and the connecting plate 52 is attached to the inner end, that is, the left end of the slide base 4 through the hole 43.
When the plate 78 is attached and removed from the slide base, the direction of the plate 78 is reversed, and when the left end of the slide base is attached, it is attached to the hole 44. The turning actuator 7 held by the turning device 8 is rotated 180° around the support shaft 84 in the space of the compressor 1llffi, the slide piece 72 is turned to the right, the rotating plate 85 is brought down together with the supporting plate 83, and the supporting frame is rotated. The support pin 77 of 76 is inserted and supported by the temporary 78, and the slide piece 72 is connected to the connection ear 67 of the rotated support cylinder 61 by the connection pin 78. When the movable fork 87 of the turning device 8 is loosened to release the restriction of the turning actuator 7, the brush device 6 can clean the right side guardrail in the same manner as when cleaning the left side. In this case, the movement direction of the movement actuator is reversed.

Also, a distance sensor 9 is installed on the right side for heavy-duty driving. Further, the brush cover 65 is rotated so as not to hit the guardrail.

When the slide base 4 is pulled to the C point position and the brush device is rotated, the brush device can be stored in the vehicle chassis while being moved to the right side.

Moreover, an air cylinder may be used as the actuator instead of a hydraulic type.

(Effects of the Invention) As described above, the present invention includes a slide base that moves along a rail provided in the lateral direction of a vehicle chassis, a brush device supported on the slide base, and an operating end connected to the brush device. The device is equipped with a turning actuator that rotates the brush device, and the turning actuator causes the brush to rotate diagonally backward from the side of the vehicle and press against the guardrail, and the device cleans the guardrail while driving in this state. The turning device is equipped with a turning device that holds the turning actuator and reverses the direction of the working end, and even when the brush device is moved to a symmetrical position on the opposite side of the vehicle, the turning device changes the direction of the working end of the turning actuator. This allows the user to not only clean the left guardrail, but also move the slide base with the brush device attached to a symmetrical position on the opposite side of the chassis, and operate the swing actuator at the moved position. By connecting the ends, the guardrail on the right side of the vehicle can be cleaned without changing the direction of travel of the vehicle, and there is no need to provide a separate brush device and the actuator can be shared, making the device simple and inexpensive. , the range of cleaning work can be expanded, and the work can be carried out safely without interfering with traffic during cleaning.
